Idea is to follow request scope more than cdi spec allows. First thought it was a concurrency utilities thing but Reza mentionned can be a CDI one so here it is.</div><div><br></div><div>Sample:</div><div>In a servlet i get MyBean which is @RequestScoped, I do some set on it. The i go async (AsyncContext) and trigger a task in another thread. It would be neat - and mandatory in some case by the loose coupling nature of CDI - to get the *same* MyBean *instance* in this thread. With a direct dependency you can easily use message passing pattern - but you loose the loose coupling cause you need to know until which level you unwrap, think t principal case which has 2-3 proxies!. However in practice you have a lot of undirect dependencies, in particular with enterprise concerns (auditing, security...) so you can't really do it easily/naturally.</div><div><br></div><div>Bonus:</div><div>One very verbose way is to be able to kind of push/pop an existing context in a thread - wrappers doing it on a Runnable/Consumer/Function/... would be neat.</div><div><br></div><div>Question:</div><div>Would CDI handle it in 2.0?</div><div><br></div><div>Side note: this is really about the fact to reuse a "context context" (its current instances map) in another thread the more transparently possible and match the user vision more than a technical question for now.</div><div><br clear="all"><div><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><br><span style="font-size:small">Romain Manni-Bucau</span><br><a href="https://twitter.com/rmannibucau" target="_blank">@rmannibucau</a> | <a href="http://rmannibucau.wordpress.com" target="_blank">Blog</a> | <a href="https://github.com/rmannibucau" target="_blank">Github</a> | <a href="https://www.linkedin.com/in/rmannibucau" target="_blank">LinkedIn</a> | <a href="http://www.tomitribe.com" target="_blank">Tomitriber</a></div></div></div></div></div></div></div></div></div></div>
